[AF_PACKET]: Fix minor code duplication

2007-11-13T05:05:20+00:00

packet_do_bind().

[AF_PACKET]: Allow multicast traffic to be caught by ORIGDEV when bonded

2007-11-11T06:03:25+00:00

The socket option for packet sockets to return the original ifindex instead
of the bonded ifindex will not match multicast traffic.  Since this socket
option is the most useful for layer 2 traffic and multicast traffic, make
the option multicast-aware.

[PACKET]: Use existing sock refcnt debugging infrastructure

2007-11-11T05:38:48+00:00

The packet_socks_nr variable is used purely for debugging
the number of sockets.

As Arnaldo pointed out, there's already an infrastructure
for this purposes, so switch to using it.

[NET]: Forget the zero_it argument of sk_alloc()

2007-11-01T07:39:31+00:00

Finally, the zero_it argument can be completely removed from
the callers and from the function prototype.

Besides, fix the checkpatch.pl warnings about using the
assignments inside if-s.

This patch is rather big, and it is a part of the previous one.
I splitted it wishing to make the patches more readable. Hope 
this particular split helped.

[PACKET]: Kill unused pg_vec_endpage() function

2007-10-19T04:58:19+00:00

The conversion to vm_insert_page() left this unused function behind,
remove it.

[NET]: Move hardware header operations out of netdevice.

2007-10-10T23:52:52+00:00

Since hardware header operations are part of the protocol class
not the device instance, make them into a separate object and
save memory.

[NET]: Wrap hard_header_parse

2007-10-10T23:52:51+00:00

Wrap the hard_header_parse function to simplify next step of
header_ops conversion.

[NET]: Wrap netdevice hardware header creation.

2007-10-10T23:52:50+00:00

Add inline for common usage of hardware header creation, and
fix bug in IPV6 mcast where the assumption about negative return is
an errno. Negative return from hard_header means not enough space
was available,(ie -N bytes).

[NET]: Make the device list and device lookups per namespace.

2007-10-10T23:49:10+00:00

This patch makes most of the generic device layer network
namespace safe.  This patch makes dev_base_head a
network namespace variable, and then it picks up
a few associated variables.  The functions:
dev_getbyhwaddr
dev_getfirsthwbytype
dev_get_by_flags
dev_get_by_name
__dev_get_by_name
dev_get_by_index
__dev_get_by_index
dev_ioctl
dev_ethtool
dev_load
wireless_process_ioctl

were modified to take a network namespace argument, and
deal with it.

vlan_ioctl_set and brioctl_set were modified so their
hooks will receive a network namespace argument.

So basically anthing in the core of the network stack that was
affected to by the change of dev_base was modified to handle
multiple network namespaces.  The rest of the network stack was
simply modified to explicitly use &init_net the initial network
namespace.  This can be fixed when those components of the network
stack are modified to handle multiple network namespaces.

For now the ifindex generator is left global.

Fundametally ifindex numbers are per namespace, or else
we will have corner case problems with migration when
we get that far.

At the same time there are assumptions in the network stack
that the ifindex of a network device won't change.  Making
the ifindex number global seems a good compromise until
the network stack can cope with ifindex changes when
you change namespaces, and the like.

[NET]: Make device event notification network namespace safe

2007-10-10T23:49:09+00:00

Every user of the network device notifiers is either a protocol
stack or a pseudo device.  If a protocol stack that does not have
support for multiple network namespaces receives an event for a
device that is not in the initial network namespace it quite possibly
can get confused and do the wrong thing.

To avoid problems until all of the protocol stacks are converted
this patch modifies all netdev event handlers to ignore events on
devices that are not in the initial network namespace.

As the rest of the code is made network namespace aware these
checks can be removed.
